We just acquired a 1993 35' Fleetwood Bounder with a factory installed reiever hitch. Does anyone know the weight capacity of this hitch? I am looking at getting a full sized motorcycle [ cruiser] lift and have been to understand that it requires a pretty heavy duty weight capacity - several thousand Lbs. I don't want to tear the back off my motor home and I sure don't want to see my bike bouncing down the road behind me. Thanks to anyone who can help me out.
